..Loss of gamma-H2AX staining (which in irradiated somatic cells is temporally linked with DSB repair) is temporally and spatially correlated with synapsis, even when this synapsis is 'non-homologous'...

..Taken together, these results strongly suggest that this gene encodes the functional homolog of yeast Spo11p, which in turn suggests that the mechanism of meiotic recombination initiation is conserved between yeast and mammals...

..To date, four mammalian proteins have been demonstrated conclusively to be involved in DSB repair by homologous recombination: Rad54, XRCC2, XRCC3 and BRCA1. This paper summarizes results from a number of recent studies...

Genetic analysis of the DNA-dependent protein kinase reveals an inhibitory role of Ku in late S-G2 phase DNA double-strand break repair

..The repair defect in XRCC2 mutant cells appears to be restricted to recombinational repair because NHEJ is normal. We conclude that XRCC2 is involved in the repair of DNA double-strand breaks by homologous recombination...

..In confirmation of peptide analysis by Stocklein et al. (1) we find that resistance to cycloheximide is due to a transversion mutation resulting in the replacement of a glutamine by glutamic acid in position 37 of L29...
